Example Embodiment
[0030] Detailed ways,
[0031]A sealed oil tank liquid level transmitter, comprising a sensor shell 1, a main splint 2, an air outlet plate 3, a secondary splint 4, a circular hole 5 of the auxiliary splint, a vent pipe 6, a lead wire 9 on the sensor, a wire protection pipe 14, Flange 17. The sensor is fixed in the sensor housing 1, the lower end of the vent pipe 6 is fastened on the air outlet plate 3, and the upper end extends above the measuring liquid level. The flange 17 is connected, and the lead wire 9 on the sensor is led out through the conduit 14 . The sensor is a differential pressure sensor. The pressure sensing surfaces on both sides of the differential pressure sensor sense the air pressure above the measured liquid surface and the pressure at the measured liquid level point in the liquid medium. The differential pressure reflects the liquid level height. In order to improve the liquid level transmitter Anti-interference ability and adapt to long-distance signa...
Example Embodiment
[0032] Example: The linear adjustment, zero point adjustment, full scale adjustment, and temperature compensation adjustment circuits of the pressure-sensitive element are integrated on the pressure-sensitive element through the integration technology of signal processing circuits such as thick-film hybrid integrated circuits or flexible circuit board integration. Integrated, so that the output of the sensor lead wire 9 is a standard current or voltage signal, and a long-distance transmission of the signal of a sealed oil tank liquid level transmitter is realized.
[0033] The sensor housing 1 is a rectangular cavity structure composed of a main plate 2 and a sub-clamp 4. The outer hexagonal screw 18a is used as a positioning member to clamp and fix the sensor, and is compacted and sealed with a sealing ring 7, and the pressure sensing on both sides of the sensor is exposed. surface to protect the sensor components and make the sensor feel differential pressure. The main splin...
